Title
(EN) AQUEOUS SUSPENSION COMPRISING A ZEOLITIC MATERIAL AND A ZIRCONIUM CHELATE COMPLEX
(FR) SUSPENSION AQUEUSE COMPRENANT UN MATÉRIAU ZÉOLITHIQUE ET UN COMPLEXE DE CHÉLATE DE ZIRCONIUM
Abstract
(EN)
An aqueous suspension comprising water, a zeolitic material and one or more of copper and iron, and a chelate complex comprising a zirconium ion and a bidentate organic ligand bonded to said zirconium ion via zirconium oxygen bonds from two oxygen atoms comprised in said ligand, said chelate complex being dissolved in the water.
(FR)
L'invention concerne une suspension aqueuse comprenant de l'eau, un matériau zéolithique et un ou plusieurs parmi le cuivre et le fer, et un complexe de chélate comprenant un ion zirconium et un ligand organique bidenté lié audit ion zirconium par l'intermédiaire de liaisons oxygène zirconium à partir de deux atomes d'oxygène compris dans ledit ligand, ledit complexe de chélate étant dissous dans l'eau.
